From the moisture absorption performance, the water absorption time of the fabric is less than 1s before washing, 5 times and 10 times, which shows that the fabric has excellent moisture absorption performance, and the moisture absorption performance is possessed by the fiber structure and is not attenuated along with the increase of the washing times. From the wicking height, the fabric is shown to have good capillary effect.
The antibacterial tests were performed on the linen-like fabrics prepared in the first and second examples. The bacteriostasis rates of the fabric prepared in the first embodiment on escherichia coli, staphylococcus aureus and candida albicans reach 99.5%, 98.4% and 90.1 respectively. The bacteriostatic rates of the fabric prepared in the second embodiment on escherichia coli, staphylococcus aureus and candida albicans reach 98.1%, 96.4% and 89.5% respectively. Thus, the antibacterial agent has good antibacterial performance.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
